Abstract:
In an embodiment, a power inverter casing (10), comprises: a body having a first component (14) removably attached to a second component (16), wherein, when joined, a recess is formed therebetween; a member (18) removably attached to the first component and the second component opposite the recess; and a handle (22) located in the recess and removably attached to the first component and the second component; wherein the member (18) contains a first member illuminating element (24), and/or the recess contains a recess illuminating element (26), and/or the handle contains a handle illuminating element (28).
Abstract:
In an embodiment, a method of making a heat sink assembly (10) can comprise: forming an heat sink assembly (10) comprising a polymer heat sink (14) around a metal insert (12), the polymer heat sink (14) comprising a thermally conductive polymer material, wherein the heat sink assembly (10) has a contact pressure between the polymer heat sink (14) and the metal insert (12); and increasing the contact pressure. In an embodiment, a method of making a heat sink assembly (10), comprises: heating a mold and subsequently introducing a metal insert to the mold, wherein the metal insert has an insert temperature of 30°C to 70°C when it is inserted into the mold; closing the mold; and in less than or equal to 0 seconds of closing the mold, over-molding the metal insert with a thermally conductive polymer material to form a heat sink assembly (10).
